Edible Film

Abstract

The present invention relates to an edible film composition comprising a waxy starch hydrolysate, a modified starch and a water-soluble polymer, and an edible film comprising the same. The present edible film may not only have an excellent film forming property, solubility and feeling in the oral cavity, but also be easily prepared at low cost, and thus be usefully used as an oral cleanser or a bad breath remover for oral cleansing, and a soluble formulation on tongue for uptake of drug in the oral cavity.
